Abstract

PURPOSE: To reject noise at signal level period and to improve S/N ratio, by taking the difference between the level of precharge period and that at signal level period, in outputting the signal charge in photoelectric conversion with a solidstate image sensor using CCD through detection.
CONSTITUTION: An output V0 picked up through photoelectric conversion with a solidstate image sensor is fed to a terminal 1a, and the output V0 is taken as the signal V0d with a delay of τd at the delay circuit 15, and this signal V0d is fed to the inverting input terminal of the differential amplifier 16. Further, the output V0 is fed to the noninverting input terminal of the amplifier 16 as it is to obtain the output difference of the both as the output of the amplifier 16. The output of the amplifier 6 is fed to the sample hold circuit 10 to hold the value at the period Tp' with the pulse SP0 in which the period of sampling pulse is τB and the precharge period Tp' of the signal Vod is at 1 level is held. Further, the signal level rejected with noise is held at the circuit 10 to improves S/N ratio by picking up the signal.
